Abstract
The invention relates to metabolically labile water-insoluble esters of formula <CHEM> wherein R<1> is a an aliphatic, araliphatic, aryl or heterocyclic group; R<2> is hydrogen or an aliphatic, aryl or araliphatic group; R<3> is as defined for R<1>, or R<3> and R<2> together form an alkylene chain; the molecule containing at least one iodine atom and being metabolised to form products which are soluble in body fluids. The esters are used in X-ray and ultrasound image enhancement.
